Re: [rules-users] unable to resolve Type Declaration class

Yeah, its in the classpath.. and to be doubly sure just before the code I do a Message s=new Message(); and that works.. so jvm can find the Message object. I have created https://jira.jboss.org/jira/browse/JBRULES-2348 I would love to know if any workarounds are possible, this has ground my project to a halt. thanks Ric Edson Tirelli-4 wrote: > > Kris just reminded me of something: do you have the actual Message > class > in the test program classpath? > > When downloading the package from guvnor, I think it does not download > the model jar... only the actual rules, etc... > > Edson > > 2009/11/25 richarda <richard.ambridge(a)gmail.com&gt; > >> >> Also tried under 5.1.0M1 release.. same issue :( >> Am i doing something wrong by declaring the @role in the Configuration >> section? >> >> >> richarda wrote: >> > >> > Still trying to get this to work. >> > I have managed to create from a default (new) guvnor setup. >> > >> > Steps I do.. >> > 1.
